“A software-based firewall that is built into the Windows OS. It allows you to control which ports will allow traffic to flow into and out of the computer”
“Solicited / unsolicited “
Too much user-friendly (millennial) made your OS so vulnerable to crack: Ex: backdoor,no security , no restrictions = hacking
Stateful Firewall: Builds up a habit of an existing conversation
– drops unwanted, unknown connections.
This means the Firewall is program to allow connections that its familiar with, and drops the connections that are unknown to the firewall, for instance, if you use Spottily to listen to music, or use Drop Box to storage, retrieve files your Firewall will allow such connection to take place, because it knows what such connections are, whereas if something like Bit Torrent wants to make a connection, because you wanted to download a program or video, then your Firewall will not recognized for the first time, and will decided to block the connection, until you allow it.
- Firewall recognizes the connection to keep flowing to go unrestricted.
- Drops unrecognized connections) protection
- Integrated into the Operating System. – Built-in on Windows –
Control Panel -> windows firewall
Advanced Settings -Windows Firewall
- Fundamental rules
Inbound / Outbound
- Based on applications
o No detailed control
- No Scope
o All or Nothing
- No connection Security rules
o NO IP filtering
Firewall behaves differently according to the type of network you will choose
Home – Work – Public.
– Basic functionality you can either allow or deny
– Before Applying changes to the firewall configurations you must present Admin rights. (UAC Control kicks in)
*EVERYTHING BY DEFAULT IS DENIED.*
Connection security rules
Down to business with the network. For a PC is simpler.
Inbound /Outbound Rules.
LOT OF CONTROL
Information -> Monitoring views.. Active connections
ALL DONE BY USING THE BUILT -IN WINDOWS FIREWALL.
Windows Firewall is probably what you would need if you are a regular user and only intent to use your computer for web browsing, making docs, viewing pictures and videos or playing video games.
By default the Windows Firewall only does what is “really” important, and that is to protect your system from “unsolicited” connections. – Block incoming connections – It does contains more however.. advanced settings, although you probably will not have to make use of them.
This is where some third-part software firewall might be more user-friendly and thus you can have a stronger secure filter. Ex: Your computer displays a message giving the option to block or allow such program.
Remember: Windows Firewall:
A software-based firewall that is built into the Windows OS. It allows you to control which ports will allow traffic to flow into and out of the computer”
Security feature, part of the OS
Back on January 11, 2013, probably one of the brightest mind of the decade committed suicide at the age of 26.
His name was. Aaron Swartz an internet activist with super technological skills. He was person devoted to the noble idea of providing information, in general academic research, to public access for everyone. At a young age Swartz was already involved giving major contribution to the web, he co-authored RSS, Creative Commons, and he also helped created Reddit among hundreds of other projects. Ultimately his most recent work was DemandPrgoress.org that was key in preventing SOPA & PIPA which might have led senators to sway sides during the day the law was supposed to pass.
In 2011, Swartz was arrested and charged with illegally obtaining academic articles by downloading JSTOR files from inside the MIT Network, he was looking to face 35 years in prison
The Internet’s Own Boy: The Story of Aaron Swartz is a documentary about his life and the importance of his contribution to the internet. The movie reminded of the value of freedom, and how we sometimes take it for granted. Before watching the movie I thought of the internet as we know it unchangeable, since nobody truly owns the internet, but that is not the case. Governments have the power to censorship its content up to some degree, which can strips us off is access. Thus violating our freedom to information, but more importantly the fact that Aaron stood up for what he believed in, and actually did make a change against the SOPA & PIPA Act. Have taught me that “we can change” It is up to us to decide the future of the internet.
I felt the motivation to take a stand for myself for what I believe in, against the odds. Aaron despite being afraid of going to jail kept on being involved as an activist demonstrating that no government is above its law.
Aaron Swartz, stood up for freedom and fairness, and because of that he was tormented to his death. His intentions with the acquired data were important to determine whether he was committing a crime or not. He as many of us believes that information should be free and accessible to anyone who desires to gain knowledge. For what is ethical about withholding a person’s lifetime of work and progress, or scientific breakthrough that could potentially lead to a solution, where is the virtue in denying the means to further educate ourselves and stunt our growth as a society. All for the sake of profit.
How did we end up like this?
After taking a quick breakfast,and appreciating the view of the blizzard through my window, I thought about BIOS on our computers and I thought if everyone using a computer really knows what the BIOS is? let alone what it is used for?
Since this bugs me, I decided to share my G+ folder about BIOS, link is down below.
A normal day like no other I learned..
- Form Factor of a PC
- ATX, BTX, Mini-ATX , IPX
- Measures and Properties of Electricity (Watt, Amps, Ohm, Volt)
- Hot, Neutral and Ground
- What resistors are..
- What diodes ares
- What capacitors are
- What transistor are
- All types and characteristics of Power Supply connections
- SAFETY measures in how to protect yourself and the equipment against electrical dangers.
- What ” surge protectors ” / ” Line conditioners” and ” Uninterruptible power supply” are and how they work.
- The best PC support Technician Tools
- Post Diagnostic Card (how to use install/use one)
- Troubleshooting the Electrical System
All topics related to the CompTIA A+ exam, additionally useful knowledge that anyone who wants to be a repair technician should know about.
P2P vs Client-Server
In P2P (peer -to peer) network (workgroup) each computer acts as either a client or server in order to share their files, I can have part I of a presentation, while someone else at another Pc has part 2, we both share files and give/request access to it.
However, if ine Pc were to go down then the files are lost for the rest of the workgroup, yet another issue is the administration of data, each person must be responsible for their own PCs therefore making it hard to manage if it were to be more than 10 hosts at a time.
On a Client-Server
In this type of network the files are stored in one place and everyone can access to them. It is easier that way as it envolves less management, less traffic among other features.
Only downside is that there is only a single point of failure. It is always good to have a backup of the data.
Earlier this afternoon after a very much needed nap, I went through my e-mail as usual, when suddenly under the Social section a rather curious e-mail was on my inbox. It talked about networking events and the basics steps that one should know (and take) whenever in a social event.
I decided it was interesting enough, so I took the time to make some slides of what I considered the most important information.
Here is it, read it and do some thinking, you may get something useful out of it — I know I did.
Before I begin I should tell you a little about myself. I am college student pursuing an Associates Degree in Computer Network Administration who is committed to learn about the world of Information Technology (IT), and a great way to begin is by getting the CompTIA A+ certification. But..
What is the CompTIA A+ or simply A+ ?!?!?
– To be simple the A+ is a non-vendor specific certification that proves that you know the basics of computer. It is a good place to start if you are new to computers or if you do not have previous experience (such as myself)
The CompTIA A+ certification is the starting point for a career in IT. The exams cover maintenance of PCs, mobile devices, laptops, operating systems and printers.
- Once you have obtained your A+ you will have a basic,but solid knowledge of how to install, maintain, customize and operate a personal computer, as well as be able to use different types of other devices without any problem.
- The A+ is also considered an entry-level computer certification and is good start to put your foot on the door in IT. As most Help-Desk Support Specialist and PC-Technicians are A+ certified.
But enough of that,and just keep in mind that if you are interested in working with computers or plan to have a career on this field … The A+ is something to keep in mind, at least for knowledge.
Let us move on to answer: How Do I get One??
I strongly suggest to visit http://www.comptia.org/
It has all the information that you need in order to schedule,prepare,and take the test. To give you and idea (because I have not taken the exam yet) it consist of two exams:
The CompTIA 200-801 & 200-802
That’s right in order to get your A+ you must pass both exams! which consist from 80 – to 90 questions each, and range from several topics from PC=Hardware all the way to Troubleshooting. Not to worry though, as the questions are multiple choice and there is more than 1 hr to finish.
Here is a small overview of what the CompTIA+ is based on. Also this is the link to check the Exam objectives
Once again if you are serious about taking the exam and actually passing you will download the exam objectives and learn every single topic.
This is pretty much covers what the A+ is and how can we get one.
Hope this has been informative for you and I like to thank you for visiting my first blog!.
Best Regards & Study Hard.
